The purpose of this thesis is to assess and compare the energy consumption and carbon footprints of two, online and offline, major movie rental services in Canada. The thesis is divided into two parts that represent two ...

In dynamic peer group communications, security has been in high demand by many applications in recent years. One of the more popular mechanisms to satisfy these security requirements is the group key scheme in which the ...

For many years, engineers have designed foundations, walls and culverts for highway and
other geotechnical applications using allowable stress design (ASD) methods. In ASD, all
uncertainties in the load and resistance ...

Caring for children with autism place mothers at high risk for poor health outcomes and compromises the health of all family members (e.g., Bristol, 1987; Hastings et al., 2005a). Although poor outcomes prevail, some mothers ...

The field of metagenomics has shown great promise in the ability to recover microbial DNA from communities whose members resist traditional cultivation techniques, although in most instances the recovered material comprises ...

The presence of subsurface anomalies, such as cavities, faults, unknown tunnels, etc., either natural or man-made, can cause public safety hazards. The detection of these features requires the development of new methods. ...

Worldwide, finfish fisheries receive increasing assessment and regulation, slowly leading to more sustainable exploitation and rebuilding. In their wake, invertebrate fisheries are rapidly expanding with little scientific ...

Given a set of peers with overlapping interests where each peer wishes to keep track
of new documents that are relevant to their interests, we propose Shrack-a self-organizing
peer-to-peer (P2P) system for document sharing ...

The study of many of glycosyltransferases is limited due to an inadequate access to sugar
nucleotides. Preparation of sugar nucleotides through the use of nucleotidylyltransferases
with broad substrate specificities is ...

Awareness and concern about the environment have been growing in recent years, and this fact has not been lost on churches. Though arguments have been made that Christianity is a cause of the world’s current ecological ...

Image matching is an important and necessary process in Content-Based Image Retrieval (CBIR). We propose three new methods for image matching: the first one is based on the Local Triplet Pattern (LTP) histograms; the second ...

Acyl carrier protein plays an essential role in bacterial fatty acid synthesis and has been recognized as an attractive new antibiotic target. In a previous study using TAP tagged ACP, we identified two ACP binding partners ...

Achieving environmental s¬ustainability in human organization is the defining challenge of the modern era. In light of the inability of the existing economic paradigm to provide for sustainability objectives, novel approaches ...

Researchers have consistently identified two distinct types of aggression: A “hot-blooded”, impulsive, reactive form of aggression, and a “cold-blooded”, premeditated, instrumental form of aggression. Despite the relevance ...

Species long-term persistence is to a great extent contingent on the ability of populations to mount variable responses to perturbations; the breadths of which are largely dependent on the amount of heritable variation ...

Empathy for others’ pain is an important human capacity. Despite this, little is known about how children develop or express their empathy for another individual’s pain. Thus, this dissertation aimed to accomplish two ...

Anisotropy in glass can lead to a transmitted double image due to birefringence. Stress-induced birefringence, the stress-optic effect, is undesirable for applications such as commercial imaging. The leading zero stress-optic ...
